如何在python中为一个if语句提供多个条件 [英] How to have multiple conditions for one if statement in python

问题描述

所以我在python 3.1.5中编写了一些代码，要求有一个以上的条件才能发生。示例：

So I am writing some code in python 3.1.5 that requires there be more than one condition for something to happen. Example:

def example(arg1, arg2, arg3):
    if arg1 == 1:
        if arg2 == 2:
            if arg3 == 3:
                print("Example Text")

问题在于，当我这样做时，如果arg2和arg3等于0，则不会打印任何内容。帮助？

The problem is that when I do this it doesn't print anything if arg2 and arg3 are equal to anything but 0. Help?

推荐答案

我会用

def example(arg1, arg2, arg3):
     if arg1 == 1 and arg2 == 2 and arg3 == 3:
          print("Example Text")

和运算符与具有相同名称的逻辑门相同;当且仅当所有输入都是1时，它才会返回1.你也可以使用或者如果你想要那个逻辑门。

The and operator is identical to the logic gate with the same name; it will return 1 if and only if all of the inputs are 1. You can also use or if you want that logic gate.

编辑：实际上，提供的代码是你的帖子对我很好。我没有看到任何问题。我认为这可能是你的Python的问题，而不是实际的语言。

Actually, the code provided in your post works fine with me. I don't see any problems with that. I think that this might be a problem with your Python, not the actual language.
